Description

  The present invention includes surfactant-based formulations, in particular polymer compositions, in particular surfactant-based cleansing compositions (including surfactants, cationic water-soluble polyelectrolytes). Surfactant-based formulations and their use in personal care and household care cleansing compositions for treating keratin substrates, textile substrates, and hard surface substrates.

  A surfactant comprising a polyelectrolyte of the present invention and a blend of such polyelectrolytes with non-cellulose cationic polysaccharide polymers such as cationic polygalactomannan polymers and derivatized cationic polygalactomannan polymers. The formulation based is based on improved transparency of the resulting formulation, keratin substrate, textile substrate, and hard surface substrate in applications such as personal care products and household care products and textile applications. Desirable for their improved conditioning, their improved adhesion of dispersed phase materials to keratin substrates, textile substrates, and hard surface substrates, their improved foaming performance, and their improved rheology .

  It has been found that personal care compositions based on surfactants containing cationic water-soluble polyelectrolytes provide good conditioning performance for hair and skin substrates. The cationic water-soluble polyelectrolyte polymer can be based on a polysaccharide backbone or a synthetic polymer backbone (eg, acrylamide, methacrylamide, acrylate ester, methacrylate ester, vinyl pyrrolidone, etc.).

  Non-cellulosic cationic polysaccharides such as cationic guar marketed under the trade name N-Hance® or Jaguar® cationic guar are shampooed, 2-in-1 or 3-in-1 conditioned Commonly used as a conditioner in products such as shampoos and body washes, laundry detergents, and shampoos, provides conditioning to the hair, conditioning to the skin, or provides conditioning, softening and antistatic features to the fabric .

  Personal care compositions containing cationic oxidized polysaccharides, including cationic oxidized guar compositions, have good conditioning performance on hair and skin substrates as described in WO 2004/091557 and US Pat. No. 7,067,499 Has been found to bring about. The molecular weight of the cationic guar can vary from 10,000 molecular weights to millions and has good performance as a conditioning agent. The use of cationic, anionic, amphoteric or hydrophobic acrylamide polymers in combination with cationic oxidized polysaccharides such as cationic oxidized guar is described in WO2004 / 091557 and US Pat. No. 7,067,499 in combination with cationic guar and WO2006 Have been described in other documents such as / 026750.

  Cationic polyelectrolyte polymers based on synthetic polymer backbones have also found use as conditioning agents and adhesives in personal care formulations. In US 5,221,530, when used alone, crosslinked quaternary acrylate / acrylamide copolymers provide good wet and dry conditioning and high levels of air bubbles in shampoos and cleansing formulations. In US Pat. No. 5,417,965, a combination with polyethyleneimine is taught.

  In US Pat. No. 5,756,436, a non-crosslinked cationic water-soluble polyelectrolyte based on a synthetic polymer backbone with a charge density of> 4 meq / g is used as a deposition polymer in a conditioning shampoo containing a water-insoluble conditioning agent. The use of has been described.

  In US Pat. No. 6,849,584, a non-crosslinked cationic water-soluble polyelectrolyte based on a synthetic polymer backbone with a charge density of> 2 meq / gram also contains a water-insoluble solid particulate material and a phase separation initiator It has been described in personal cleansing compositions.

  In US Pat. No. 6,495,498 cleansing compositions containing combinations of cationic polyelectrolyte polymers have also been described, one polymer being a cationic polygalactomannan, such as a cationic guar, and another The polymer may be a cationic water-soluble synthetic copolymer in the presence of a water-soluble silicone conditioning agent.

  In WO2007 / 065537, an aqueous shampoo composition containing a combination of cationic polymers containing dispersed phase droplets (<4 micron droplet diameter) of a water-insoluble conditioning agent has also been described, one type The polymer may be a cationic polygalactomannan, such as a cationic guar, and another polymer may be a cationic acrylamide copolymer having a charge density of <1 meq / gram.

  In WO2008 / 129493 a personal cleansing composition containing a combination of cationic polymers is also described, one polymer being a cationic polymer having a charge density of <4 meq / g, and an anionic surfactant Forming an isotropic coacervate, the second cationic polymer has a charge density of> 4 meq / g and forms a lyotropic liquid crystal in combination with an anionic surfactant.

  Although these references indicate that cationic polyelectrolyte polymers based on synthetic polymer backbones can provide conditioning and enhance adhesion of silicone and zinc from surfactant-based formulations, Commercially available cationic synthetic polyelectrolyte polymers distributed in the United States have higher molecular weights, resulting in “thread-like” rheology in surfactant-based formulations. The lower MW cationic synthetic polyelectrolyte polymer currently on the market has several weaknesses such as reduced solubility, reduced transparency and reduced adhesion performance in surfactant-based formulations. Also have. Commercially available cationic, anionic, and nonionic synthetic polyelectrolytes also contain high levels of residual monomers (such as acrylamide monomers). There is a need to reduce residual monomer levels in these compositions to low levels.

  Furthermore, the hydrolytic stability of cationic synthetic polyelectrolytes such as cationic (meth) acrylic acid ester polymers is an important aspect of their performance in aqueous formulations. In DE3544909, cationic synthetic polyelectrolyte polymers derived from poly (meth) acrylates are susceptible to hydrolysis of ester functional groups in aqueous solution and range from several hours to several days at pH values of 6-7.5. Have a lifetime of. Furthermore, these cationic synthetic polyelectrolyte polymers have high acute aquatic toxicity due to their charge density. These polymers have much lower ecotoxicity when the ester functionality is hydrolyzed. See Chang et al., “Water Science Technology”, 44, 2-3, 461-468, 2001.

  In US7375173, the entire disclosure of which is incorporated herein by reference, an improved ecotoxic cationic synthetic polyelectrolyte terpolymer is described as (meth) acrylamide, a quaternized (meth) acrylamide derivative, It has been found that it can be prepared from the polymerization of monomers of and (meth) acrylic acid derivatives and / or hydrolysis-stable cationic monomers. This knowledge is incorporated herein by reference and incorporated as part of the disclosure.

  Wet and dry measurements are typical test methods used to measure conditioning performance in shampoo and conditioner applications. Commercially available conditioning polymers currently on the market have been reported to reduce the wet combing force experienced by dry hair combing by 30% to 80% relative to polymer-free shampoos. .

  Conditioning performance in shampoo applications can also be measured by monitoring the decrease in light transmission of a clear shampoo or cleansing formulation containing the conditioning polymer due to increased dilution with water. The greater the drop in permeability due to dilution with water, the greater the level of adhesion. Reduced formulation transmittance or reduced optical clarity is associated with precipitation of conditioning polymer from shampoos or other cleansing formulations. The conditioning polymer can be applied in the form of a complex with a surfactant in the formulation or in a non-complexed form.

  Silicone, other conditioning oils or functional materials attached from shampoos, conditioners, or colorant systems to hair or scalp, cleansing or conditioning body wash to skin, or surfactant based laundry formulations to fabrics, The amount of zinc, or other activity, or performance material is also a measure of the conditioning or deposition performance of the conditioning or deposition polymer. Uniformity or non-uniformity of silicone, other conditioning oils or conditioning materials, zinc, fragrances, or other “active” materials has a significant impact on the perceived performance of cosmetic formulations obtain. Adhesion profile: 1) Hair fiber (attachment along the fiber from the root to the tip recovers damage in the area towards the tip or end of the hair fiber and attaches a uniform color from the hair coloring formulation; Required to maintain color uniformity along the fiber); 2) Dry, damaged areas of the skin, especially the skin (oils, other conditioning agents, active materials (such as antibacterial agents), Adhesion of sunscreen actives, or colorants (such as self-tanning ingredients) is required for uniformity to occur); and 3) fabrics (adhesion particularly damages fabrics such as wool, cotton, polyester, etc.) It is particularly important on substrates such as those that occur on a received or worn area.

  In skin care applications, skin smoothness or reduced or softer skin feel, reduced water vapor transmission and improved skin elasticity are test methods used to measure skin conditioning. In surfactant-based household cleansing product formulations where conditioning performance is desirable (such as dishwashing detergents, laundry detergents, fabric softeners, and antistatic products), conditioning is done manually with liquid tableware soap. It means giving a soft feel, or giving the fabric a soft feel with a laundry detergent or fabric softener, eliminating electrostatic effects and removing deformations known as fabric fiber breaks or flaking. It is also important and can be measured to give the fabric a color retention or a vibrant property of color.

  Commercially available cationic water-soluble synthetic polyelectrolyte polymers have been shown to provide conditioning and enhance silicone and zinc adhesion from surfactant-based formulations, but are commercially available Commercially available water-soluble synthetic polyelectrolyte polymers have a high molecular weight, and as a result, impart thread-like rheology to surfactant based formulations. The lower MW cationic water-soluble synthetic polyelectrolyte polymers in the market are less transparent in surfactant-based formulations, in surfactant-based formulations. It has several weaknesses such as reduced solubility and reduced adhesion performance in surfactant based formulations.

  Cationic water-soluble polyelectrolyte polymers based on non-cellulose cation-modified polysaccharides and synthetic backbones are active as conditioning polymers in surfactant-based cleansing formulations and for conditioning oils and hair and skin Although known to function as adhesion aids for providing treatments, repeated use of these polymers results in unwanted accumulation of conditioning ingredients such as silicone and other oils on the hair or skin. obtain. This accumulation is manifested as an increase in the energy required to comb dry hair and as a sticky feel to the hair. In addition, these polymers provide conditioning at the root ends of the hair fibers, but provide a more uniform adhesion of silicone and other active agents along the length of the hair fibers (the fibers are more There is a need to make polymer compositions that are damaged and require more conditioning). Finally, in areas where anti-dandruff and antibacterial active materials are delivered to the scalp, increase the efficiency of delivery of antibacterial compounds from surfactant systems (such as shampoos and hand cleansers) and to the scalp and skin There is a need to keep antimicrobial compounds in place for better targeted delivery, as well as long-term activity.

  Materials (silicone, perfume, zinc, from surfactant-based formulations without the undesirable thread-like aspects imparted to the formulation by the surfactants or polymers used in these formulations. There is a need for improved adhesion and adhesion profiles of hair and scalp (such as other active materials). The foam or foam properties of the composition are maintained or improved, improving the amount of adhesion for oily phases such as silicones, perfume oils, mineral oils, and particulate materials such as zinc pyrithione, zinc carbonate, and other active materials There is also a need for surfactant-based formulations.

  There is also a need for polymer compositions containing lower levels of residual monomer.

The present invention is based on standard viscosity measurements where the polymer is measured in deionized water at 30 rpm using a Brookfield viscometer, spindle # 4, at a concentration of 1.5 wt% polymer,> 0.001 meq / g and 4 meq / Cationic water-soluble polyelectrolyte composition, in particular a surfactant-based conditioning or cleansing composition, comprising a cationic water-soluble polyelectrolyte having a charge density of less than g and a solution viscosity of 10 mPas to 3000 mPas . Cationic water-soluble polyelectrolytes are synthesized by adiabatic gel polymerization processes or as water-in-water dispersions, and copolymers and terpolymers of (meth) acrylamide, and cationic monomers based on (meth) acrylamide, and / or Alternatively, it comprises a hydrolysis-stable cationic monomer and / or a monomer based on a cationic (meth) acrylic ester. The cationic water-soluble polymer electrolyte shows the following.
(1) In contrast to the elastic rheology associated with higher MW cationic water-soluble polyelectrolytes in the prior art, conditioning is maintained while maintaining a less “thread-like” rheology in the formulation Enhanced adhesion of silicone or conditioning agents to hair and keratin substrates, textile substrates, and hard surface substrates from shampoo formulations or cleansing formulations, and silicone or conditioning agents to damaged areas of the substrate More targeted deposition, or more uniform deposition of a substrate, for example silicone or conditioning agent over the length of the hair fiber,
(2) Enhanced adhesion of anti-dandruff active agents such as zinc to the scalp, or skin of other antimicrobial agents from antimicrobial formulations when compared to higher MW cationic water-soluble polyelectrolytes in the prior art Improved aesthetic aspects of cleansing experience, such as adhesion of hard surfaces to substrates, and foam generation and texture, and
(3) solubility in surfactant-based systems, enhanced transparency, and improved adhesion profile when compared to higher MW cationic water-soluble polyelectrolytes in the prior art;
(4) Lower residual monomer levels when compared to other synthetic polyelectrolyte polymers in the prior art.

  In the present invention, (A) a cationic water-soluble synthetic polyelectrolyte polymer, in particular, a cationic acrylamide polymer having a cationic charge density of more than 0.001 meq and less than 4 meq / g per gram at pH 7, and (B) a non-cellulose cation A composition comprising a combination of one or more cationic polymers selected from modified polysaccharides, a cationic polymer selected from, and an acid or base component (1) without pH adjustment and without aggregation (2) The aqueous composition or polymer blend composition thus obtained is formulated into a surfactant composition such as a cleansing composition. To produce a formulation that exhibits enhanced adhesion of the dispersed phase ingredients (silicone, zinc pyrithione, fragrances, colorants, and other active ingredients) to the substrate (hair, skin, fabric, etc.) It has also been found that (3) the formulation exhibits a reduced thread-like aspect and improved aesthetics (such as bubble and foam generation).

  The enhanced adhesion of the dispersed phase material is independent of the particle size of the dispersed phase material.

  The viscosity of the aqueous solution of the cationic acrylamide polymer correlates with the molecular weight of the cationic acrylamide. When the viscosity of the cationic acrylamide polymer is reduced to less than 200 mPas (@ 1 wt% polymer solids; spindle # 1, 10 rpm, @ 20 ° C. in 10% NaCl), a formulation based on cationic acrylamide polymer based on surfactant The “thread-like” rheology imparted to is significantly reduced.

  Cationic polygalactomannan in a ratio of about 0.001 to 10 cationic acrylamide / wt galactomannan polymer, acid (citric acid, fumaric acid, adipic acid, and other neutralizing acids) and base (such as sodium bicarbonate) Is a dry powder composition that readily disperses in water and produces a smooth aqueous polymer solution. This composition in the form of an aqueous polymer solution or dry powder composition can be added directly to a personal or household care formulation (such as a surfactant-based formulation) to improve silicone adhesion, yarn-like, etc. Compositions can be produced that exhibit reduced morphology and improved foaming and foam performance. The polymer solution or dry powder composition can also be used in textile applications, oil recovery applications, paper applications, and coating applications.

  This composition is useful in formulating cosmetic or personal care compositions, particularly cleansing compositions (body wash, shampoo formulations, etc.), as well as conditioner compositions. The composition is also useful in formulating household care compositions, textile care compositions, paper compositions, paper coating compositions, and coating compositions.

  The advantages of using this composition over individual polymers are not associated with undesirable “thread-like” rheological adverse effects, especially in personal and home care compositions, with improved foam and foaming performance. Improved adhesion of the dispersed phase from the surfactant-based system, and improved conditioning performance provided by the composition. Aqueous formulations without pH adjustment and without agglomeration due to the additional advantage of blending a specific molecular weight and charge density cationic water-soluble synthetic polyelectrolyte with a specific molecular weight and charge density non-cellulose cationic polysaccharide polymer Both result in a composition that disperses easily. The composition does not impart elastic “thread-like” rheology to surfactant-based formulations. In contrast, higher MW cationic acrylamide polymers typically dissolve and provide a “thread-like” rheology to the formulation. In contrast, the compositions of the present invention result in a more desirable rheology and yarn-like aspect reduction in the formulation.

  The composition of the present invention is formulated into a surfactant composition such as a cleansing composition to have a reduced yarn-like aspect and improved aesthetics (such as bubble and foam generation) while the active ingredient Formulations can be produced that achieve improved adhesion. The compositions of the present invention can also be formulated into conditioning formulations such as hair conditioners to achieve smoothness and reduced tangling during wet and dry combing of hair.

  Surfactant-based conditioning or cleansing compositions comprising the cationic water-soluble polyelectrolytes of the present invention and combinations of these cationic water-soluble polyelectrolyte polymers with non-cellulose cationic polysaccharides or derivatives thereof The object maintains damaged rheology while maintaining less rheology, as opposed to the elastic rheology associated with higher MW cationic water-soluble polyelectrolytes in the prior art. Improved smoothness as measured by dry combing and tribometry, resulting in improved uniformity or targeted delivery of silicone adhesion along the hair fiber for all hair types, including bleached hair Brings softness or softness to the hair, with silicone and non-silicone creasing When delivered from a ging composition, it provides improved combing performance and improved aesthetic aspects of cleansing experience, such as foam generation and texture, and anti-dandruff agent (zinc pyrithione) on artificial skin (as a model of the scalp) And enhanced delivery of zinc carbonate, etc.) has been shown.

  Borates, aluminum salts, copper, iron, calcium, as disclosed in U.S. Patent Application Publication Nos. 2008-0112907A1 and 2008-0112906A1, the disclosures of which are incorporated herein by reference. And crosslinking agents based on sodium salts, glyoxal, and metal salts based on titanium and zirconium, and polyols or polysaccharide polymers (cationic water-soluble polyelectrolyte polymers and non-cellulose cationic polysaccharides or derivatives thereof) It has also been found that the application of the combination with (as a surface coating to the polymer combination) improves the dispersibility and dissolution performance of the compositions of the invention.

  These compositions also include other effective active materials (dyes or dyes, antidandruff agents (such as selenium and salicylic acid), fragrances, antimicrobial materials, UV protectors, sunblocks, hair growth agents, etc.), scalp, hair It is expected to provide improved adhesion to and to hair, skin, other keratin substrates, textile substrates, and hard surface substrates.

FIG. 5 is a graph showing the pre-wash distribution by SLES-3EO of total silicone deposited from conditioning shampoo and untreated brown hair. It is a graph which shows the zinc adhesion from an anti-dandruff model shampoo, and the effect of Zn (average) ppm-silicone particle size (30 μ vs 0.3 μ dimethicone).

  The surfactant-based compositions of the present invention include cationic and active ingredients in combination with surfactants and active ingredients typically included in household care compositions, textile care compositions or personal care compositions. Water-soluble polyelectrolyte is included. In a second embodiment of the present invention, the surfactant-based system further comprises a cationic polysaccharide in addition to the cationic water-soluble polyelectrolyte and the surfactant, the composition comprising: It is particularly effective in increasing the adhesion of the dispersed phase of the composition.

  Cationic water-soluble polyelectrolytes include (1) copolymers of (meth) acrylamide and cationic monomers based on (meth) acrylamide and / or hydrolysis-stable cationic monomers, (2) (meth) acrylamide Terpolymers, monomers based on cationic (meth) acrylic acid esters, and monomers based on (meth) acrylamide and / or hydrolysis-stable cationic monomers. Throughout this application, the term (meth) acrylamide means methylacrylamide and acrylamide and (meth) acrylic acid means acrylic acid and methacrylic acid.

  Cationic water-soluble synthetic polyelectrolytes have a total charge density of about 0.001-4 meq / g, preferably about 1.0-2.5 meq / g, more preferably about 1.5-2.2 meq / g, and their solution viscosity is Measured as a 1% solution in deionized water, 10 to 3000 mPas, preferably 80 to 2000 mPas, more preferably 90 to 1500 mPas. Furthermore, the molecular weight as measured by size exclusion chromatography is about 500,000 to 2 million, generally about 1 million, as described herein below.

Cationic monomers based on (meth) acrylic acid esters include cationized esters of (meth) acrylic acid containing quaternized N atoms. Preferably (having a C ₁ -C ₃ in the alkyl and alkylene groups) quaternized dialkylamino alkyl (meth) acrylate, in particular, quaternized with methyl chloride was dimethylaminomethyl (meth) acrylate, dimethyl Aminoethyl (meth) acrylate, dimethylaminopropyl (meth) acrylate, diethylaminomethyl (meth) acrylate, diethylaminoethyl (meth) acrylate and ammonium salts of diethylaminopropyl (meth) acrylate are used. Particular preference is given to alkyl halides, in particular dimethylaminoethyl acrylate quaternized with methyl chloride or benzyl chloride or dimethyl sulfate (ADAME-Quat).

The cationic monomers based on (meth) acrylamides include quaternized dialkylaminoalkyl (meth) acrylamide (with the C ₁ -C ₃ in the alkyl or alkylene group). Particular preference is given to alkyl halides, in particular dimethylaminopropylacrylamide quaternized with methyl chloride or benzyl chloride or dimethyl sulfate.

  The hydrolysis-stable cationic monomer may be any monomer that can be considered stable for the OECD hydrolysis test in addition to the dialkylaminoalkyl (meth) acrylamide described above. Examples are diallyldimethylammonium chloride or water-soluble, cationic styrene derivatives.

  Particularly preferred as cationic polyelectrolytes according to the invention are acrylamide, 2-dimethylammonium ethyl (meth) acrylate quaternized with methyl chloride (ADAME-Q) and 3-dimethyl quaternized with methyl chloride. It is a terpolymer of ammonium propyl (meth) acrylamide (DIMAPA-Q). Another preferred polyelectrolyte is formed from acrylamide and acrylamidopropyltrimethylammonium chloride having a charge density of 1.0 to 3.0 meg / g.

  The polymer electrolyte can be synthesized by a known method such as emulsion polymerization, solution polymerization, gel polymerization and suspension polymerization, preferably gel polymerization and solution polymerization. By controlling the method of polymerization, the concentration of unreacted residual monomer in the final product can be controlled. In general, it is desirable to have less than about 0.04%, preferably less than 0.02%, most preferably less than 0.01% residual monomer present in the polyelectrolyte. We have found that further post-polymerization processing steps further reduce the unreacted residual monomer in the polyelectrolyte product to less than about 0.005%.

  Preferably, such polyelectrolytes comprise cationic monomers based on (meth) acrylic acid esters, and monomers based on (meth) acrylamides and / or hydrolysis-stable cationic monomers and (meth) acrylamides. It is synthesized by mixing the combination and initiating the polymerization. During polymerization, a solid gel is formed from the monomer solution followed by grinding, drying and grinding.

  The polymerization is preferably carried out as adiabatic polymerization, which can be initiated by a redox system or by a photoinitiator. Furthermore, a combination of both starting methods is possible. The redox initiator system consists of at least two components (an organic or inorganic oxidant and an organic or inorganic reductant). In many cases, compounds containing peroxide units are used for this purpose. Examples are inorganic peroxides (alkali metal and ammonium persulfate, alkali metal and ammonium perphosphate, hydrogen peroxide and its salts, in particular sodium peroxide and barium peroxide), or organic peroxides (benzoyl peroxide). And butyl hydroperoxide), or peracid (such as peracetic acid). In addition, however, other oxidizing agents such as potassium permanganate, sodium chlorate and potassium chlorate, potassium dichromate can also be used. As reducing agents, use sulfur-containing compounds such as sulfites, thiosulfates, sulfonic acids and organic thiols (such as ethyl mercaptan and 2-hydroxy-ethanethiol), 2-mercaptoethylammonium chloride, thioglycolic acid and others be able to. In addition, ascorbic acid and low-valent metal salts, preferably copper (I), manganese (II) and iron (II) salts can also be used. Phosphorus compounds such as sodium hypophosphite can also be used. In the case of photopolymerization, the reaction is initiated by UV light that causes decomposition of the initiator. Initiators include benzoin and benzoin derivatives (such as benzoin ether), benzyl and its derivatives (such as benzyl ketal), acryldiazonium salts, azo initiators (2,2 ''-azobis (isobutyronitrile) and 2,2 ' '-Azobis (2-amidinopropane) hydrochloride, etc.) or acetophenone derivatives can be used. The amount of oxidizing and reducing component may range from 0.00005 to 0.5 weight percent, preferably from 0.001 to 0.1 weight percent, preferably from 0.001 to 0.1 weight percent, based on the monomer solution. For photoinitiators, it can range from 0.001 to 0.1 weight percent, preferably from 0.01 to 0.08 weight percent.

  For example, as described in DE 3544770, the polymerization is carried out batchwise in an aqueous solution in a polymerization vessel or continuously on an endless belt. This step is introduced as a reference step and incorporated as part of the disclosure. The process starts at a temperature of -20 to 50 ° C, preferably -10 to 10 ° C and is carried out at atmospheric pressure without an external heat supply. Depending on the heat of polymerization, a maximum final temperature of 50-150 ° C. is achieved depending on the content of polymerizable substances.

  When the polymerization is complete, the polymerized product obtained in the form of a gel is ground.

  The crushed gel is now dried batchwise in an air circulating drying oven at 70-150 ° C., preferably 80-130 ° C. Drying can be carried out continuously in the same temperature range on a band drier or in a fluid bed drier.

The above list of personal care and home care active ingredients or benefit agents is merely an example and is not a complete list of active ingredients that can be used. Other ingredients used in these types of products are well known in the art. In addition to the above-mentioned components used conventionally, the composition according to the invention also comprises colorants, preservatives, antioxidants, nutritional supplements, alpha or beta hydroxy acids, activity promoters, emulsifiers, functional polymers, thickening agents. agents (salt, i.e., NaCl, NH ₄ Cl, and KCl, water-soluble polymers, i.e., hydroxyethylcellulose and hydroxypropylmethylcellulose, and fatty alcohols, i.e., cetyl alcohol), alcohols having 1-6 carbons, fats Or optionally including ingredients such as aliphatic compounds, antibacterial compounds, zinc pyrithione, silicone materials, hydrocarbon polymers, emollients, oils, surfactants, pharmaceuticals, flavors, perfumes, suspending agents, and mixtures thereof be able to.

  According to the present invention, silicone materials that can be used are polymers, oligomers, oils, waxes, resins, or gums or polymers that can be used in personal care compositions, household care compositions or institutional care compositions. Polyorganosiloxanes, which may be in the form of organosiloxane polyether copolyols, amodimethicone, cationic polydimethylsiloxane materials and any other silicone material. The cationic water-soluble synthetic polyelectrolyte compositions useful in the present invention can be used as conditioning agents in 2-in-1 shampoos, conditioners, body lotions, sunscreens, anti-shrink and hair styling formulations. Cationic water-soluble synthetic polyelectrolyte compositions useful in the present invention are also used for hair volume, ease of handling, hair repair or color retention, skin humidification and moisture retention, perfume retention, hair Improve the long-term retention of sunscreen on skin and fabric, improve flavor enhancer and antibacterial performance in oral care applications, improve fabric abrasion resistance (wear resistance) and discoloration resistance in household applications Can do.

  The composition can be formulated based on the end use product. Different formulations may require different order of addition to achieve the desired end product with the desired characteristics.

  According to the present invention, the benefits of conditioning cationic water-soluble synthetic polyelectrolytes are demonstrated as conditioning agents in personal care compositions such as hair care and skin care compositions. Performance also includes oral care compositions (such as toothpastes, oral rinses, caries prevention mouth rinses, and antibacterial mouth rinses), and household care compositions (washing cleaner and softener products for textile substrates, and hard Expected for surface cleaner products).

  According to the present invention, a functional system substrate is defined as a material associated with personal care and home care applications. In personal care, the substrate may be skin, hair, teeth, and mucous membranes. In household care products, the substrate may be a hard surface (such as metal, marble, ceramics, granite, wood, hard plastic, and wallboard), or a soft surface (such as textiles and fabrics).

  The formulations are particularly useful as deposition aids for dispersed phase compositions such as the personal care ingredients listed above for use on damaged hair or on the scalp or skin. Damage by incorporating a formulation comprising a synthetic cationic polyelectrolyte of the present invention into a dispersed phase composition (silicone or jojoba oil, meadowfoam seed oil, etc.), or in combination with an anti-dandruff active agent (such as zinc pyrithione). The amount of oil deposited on the received hair and scalp, and the amount of anti-dandruff active deposited on the scalp is increased. Such compositions also include surfactants and suspending agents that retain the oil or other dispersed phase suspended in the composition as droplets or particles. When diluted during use, these particles or droplets deposit on the substrate. Formulations of the present invention having a synthetic cationic polyelectrolyte can increase oil adhesion on damaged hair from 100 ppm to 1000 ppm.

  One particular embodiment of the present invention further comprises a non-cellulose cation modified polysaccharide. The combination of synthetic polyelectrolyte and non-cellulose cationic modified polysaccharide further improves the adhesion of conditioning agents and active ingredients.

  In this embodiment, the composition is a combination of cationic water solubility, synthetic polyelectrolyte and non-cellulose cation modified polysaccharide. Non-cellulose cation modified polysaccharides may contain varying amounts of protein as part of their composition. According to the present invention, a non-cellulose cation modified polysaccharide, more specifically a polygalactomannan composition or polyglucomannan composition containing a quaternary ammonium group covalently bonded to the polysaccharide backbone, has a lower limit of about 0.0005. And an upper degree of cationic substitution (DS) of about 3.0. Preferably, the lower limit of the cationic DS is 0.001, more preferably 0.002, and still more preferably 0.01. Preferably, the upper limit of the cationic DS is 3.0, more preferably 1.0, and still more preferably 0.35. The cationic polygalactomannans or derivatives thereof of the present invention generally have a weight average molecular weight (MW) having a lower limit of about 10,000 and an upper limit of about 2,000,000. Preferably, the lower limit of molecular weight is about 100,000, more preferably about 200,000. Preferably, the upper limit of molecular weight is about 1,500,000, more preferably about 1,000,000.

  According to the present invention, non-cellulose cation-modified polysaccharides, more preferably cationic polygalactomannans or cationic derivatized polygalactomannans are present in the presence of crosslinking agents (boron, glyoxal, etc.), or non-cellulose cation-modified polysaccharides, It can have other treatments that make it easily dispersible without agglomeration in water. The crosslinker content may be less than 5% by weight, preferably less than 1% by weight per gram of non-cellulose cation modified polysaccharide. The crosslinker may also be of a type that can form irreversible covalent crosslinks with the polymers of the present invention, resulting in a product that has more swelling performance in aqueous systems.

  The polygalactomannan gum from which the non-cellulose cation-modified polysaccharide of the present invention is derived is selected from the group consisting of guar, locust bean, tara gum, red croaker, cassia, and Spodoptera. Other non-cellulose polysaccharides useful in the present invention include xanthan gum, gellan gum, welan gum, rumzan gum, konjac mannan, gum arabic, soy polysaccharides, xylofructose gum and tamarind gum.

  The cationic functional group of the non-cellulose cation-modified polysaccharide can be added to the skeleton by a known method. For example, non-cellulosic polysaccharides such as polygalactomannan can be combined with a first quaternary ammonium alkylating reagent (such as 3-chloro-2-hydroxypropyltrimethylammonium chloride and 2,3-epoxy-propyltrimethylammonium chloride). The reaction can be carried out for a sufficient time and at a sufficient temperature. Preferred examples include a combination of two glycidyl trialkylammonium salts or 3-halo-2-hydroxypropyl trialkylammonium salts, where the first quaternary ammonium reagent is glycidyl trimethyl ammonium chloride, glycidyl triethyl ammonium Chloride, glycidyltripropylammonium chloride, glycidylethyldimethylammonium chloride, glycidyldiethylmethylammonium chloride, and their corresponding bromides and iodides; 3-chloro-2-hydroxypropyltrimethylammonium chloride, 3-chloro-2-hydroxypropyltriethyl Ammonium chloride, 3-chloro-2-hydroxypropyltripropylammonium chloride, 3-chloro-2-hydroxypropylethyldimethylammonium chloride And their corresponding bromides and iodides; and quaternary ammonium compounds (such as halides of imidazoline ring-containing compounds).

  Non-cellulose cation-modified polysaccharides also have other substituents, such as non-ionic substituents, i.e., hydroxyalkyl (alkyl is a linear or branched hydrocarbon moiety having 1 to 30 carbon atoms. (E.g., hydroxymethylhydroxyethyl, hydroxypropyl, hydroxybutyl), alkyl, aralkyl, or aryl groups (alkyl represents a linear or branched hydrocarbon moiety having 1 to 30 carbon atoms) Or an anionic substituent (carboxymethyl group, sulfonic acid group, or phosphonic acid group). These optional substituents are attached to the non-cellulose polysaccharide by reaction with a reagent, e.g., for example, (1) alkylene oxide (e.g., ethylene oxide, propylene oxide, butylene oxide), hydroxyethyl group, hydroxy Propyl group or hydroxybutyl group is obtained, or (2) chloromethylacetic acid is used to obtain a carboxymethyl group, or (3) chloroethylsulfonic acid is used to obtain a sulfonic acid group, or (4) chloroethyl is obtained. Phosphonic acid groups are obtained with phosphonic acid. Methods for preparing non-cellulose derivatized polysaccharides are well known in the art. The non-cellulose cation modified polysaccharide may also contain a mixture of one or more other substituents such as nonionic, anionic and cationic substituents.

  In accordance with the present invention, examples of functional polymers that can be used in blends with the non-cellulose cation-modified polysaccharides of the present invention include water soluble polymers such as acrylic acid homopolymers such as Carbopol® products. And anionic and amphoteric acrylic copolymers, vinylpyrrolidone homopolymers and cationic vinylpyrrolidone copolymers; nonionic, cationic, anionic and amphoteric cellulose polymers (hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, hydroxypropylmethylcellulose, cationic Hydroxyethyl cellulose, cationic carboxymethyl hydroxyethyl cellulose, and cationic hydroxypropyl cellulose); acrylamide homopolymer, And cationic, amphoteric and hydrophobic acrylamide copolymers, polyethylene glycol polymers and copolymers, hydrophobic polyethers, hydrophobic polyether acetals, hydrophobically modified polyether urethanes, and other polymers called associative polymers, hydrophobic cellulose Polymers, polyethylene oxide-propylene oxide copolymers, and nonionic, anionic, hydrophobic, amphoteric and cationic polysaccharides such as xanthan, chitosan, carboxymethyl guar, alginate, gum arabic, nonionic, cationic, anion And amphoteric guar polymers (hydroxypropyl guar, hydrophobic guar polymer, carboxymethyl guar hydroxypropyltrimethylammonium chloride, guar hydroxypropyl chloride) Ammonium chloride, and hydroxypropyl guar hydroxypropyl trimethyl ammonium chloride, etc.).

  The ratio of synthetic polyelectrolyte to non-cellulose polysaccharide ranges from 99: 1 polysaccharide: synthetic polyelectrolyte to 1:99 polysaccharide: synthetic polyelectrolyte based on weight. In general, the combination of polysaccharide and synthetic polyelectrolyte is 5-30% by weight synthetic polyelectrolyte and 95-70% by weight polysaccharide. This combination can be blended with the surfactants, solvents and active ingredients discussed above to formulate an improved home or personal care composition.

  Compositions having a synthetic cationic polyelectrolyte and a cationic polysaccharide are particularly suitable for the attachment of oily components to substrates other than damaged hair. For example, by using this combination with an oily composition, the oil phase deposition can be increased from about 500 ppm to about 1200-1500 ppm. This makes it possible to use less oil in the formulation as more oil in the formulation is actually deposited.

  This composition can incorporate any of the conditioning oils or other conditioning agents discussed above and, of course, is used with any of the non-conditioning benefit agents discussed above, and cleaning compositions as discussed above. Products, personal care product compositions, home care product compositions, or institutional care product compositions can be formulated.

  For a more detailed understanding of the present invention, reference may be made to the following examples, which are intended as a further illustration of the invention but are not to be construed in a limiting sense. All parts and proportions are by weight unless otherwise specified.

(Example)
A series of lower molecular weight cationic polyacrylamide polymers have been previously incorporated herein by reference to achieve improved aesthetic performance, including reduced yarn-like aspects and improved adhesion performance. Prepared by the adiabatic gel polymerization procedure described in US Pat. No. 7,375,173.

Blend preparation method
In Examples 10, 11, and 12 of Table 1, the following general method was used for the preparation of blend materials. This same method was used for the preparation of all blend materials described in the Examples section.

  The cationic guar polymer was used as received. The cationic synthetic polyelectrolyte of the present invention was ground on a Netzsch Condux CUM150 Universal Mill configured with a Blast Rotor operating on a 0.2 micron Connidur screen and an 8000 RPM mill to produce a powder (50-60 μm). The ground form of the cationic polyacrylamide was measured by liquid chromatography as described in the method section, with a reduced content of residual acrylamide monomer (12 ppm) relative to the original unground sample (183 ppm). Had.

  The dry polymer powder was then mechanically blended using a ribbon blender or Long Roll Jar Mill. A solution of 25-50 wt% aqueous citric acid was sprayed onto the blended mixture using a similar spray blender (Cuisinart 14 cup food processor, Tuthill pump, spray gun, and scale). In order to reach the desired moisture (6-8% moisture), the blend was dried using a fluid bed dryer.

  The blend was tested for homogeneity using standard NMR methods.

(Examples 1 to 14)
In shampoo formulations containing 12% sodium lauryl ether sulfate / 2% cocamidopropyl betaine surfactant blend, high molecular weight high viscosity cationic properties as shown in Examples 2-3 in Table 1 The shampoo formulation containing the acrylamide polymer contained undissolved gel remaining even after a long dissolution time.

  The solubility of the lower molecular weight cationic acrylamide polymers prepared by the adiabatic gel polymerization process is the absence of gel and turbidity in the shampoo formulations thus obtained for the polymers of the present invention in Examples 8 and 9. Significantly improved) as indicated by higher transparency. The polymers of the invention in Examples 8 and 9 can be used in shampoo formulations even when compared to lower MW cationic acrylamide polymers prepared by solvent polymerization (Example 5) or emulsion polymerization processes (Example 4). Shows improved solubility and transparency.

  It is important to note that the shampoo in Example 5 contained undissolved gel even after a long dissolution time, regardless of the low aqueous viscosity or molecular weight for this polymer. It was determined that this polymer was prepared by a solvent polymerization process rather than the adiabatic gel polymerization process used for the polymers in Examples 1-3 and 6-9.

  The improved solubility in shampoo and the target molecular weight for improved performance were identified as polymer viscosities in Examples 8 and 9. The polymers of Examples 8 and 9 have similar viscosities as the polymers in Examples 4 and 5 of Table 1. However, as shown in Table 1 and Table 2, the polymers of the present invention in Examples 8 and 9 are shown in Table 1 and Table 2 Have better clarity and solubility in surfactant based formulations such as shampoo and body wash formulations.

  The polymer solution viscosity data in Table 1 is used for comparison of polymer molecular weight. As noted above, the polymers of Examples 4 and 5 have similar viscosities to the polymers of the present invention in Examples 8 and 9, but the polymers of Examples 4 and 5 are Table 1 and Table 2 The polymers of the present invention in their solubility in surfactant-based systems, as shown by the transparency value of shampoos expressed in Table 2 as% transmittance (% T) at 600 nm And different.

  Further differences between the polymers of the present invention and the polymer of Example 5 were noted in the measurement of particle shape and spherical particle content that further distinguishes these polymers. The shape factor of these polymer particles was measured by using PartAn2001L, an optical image analysis system, non-spherical parameters (NSP). These measurements showed a deviation of approximately 14% NSP from the ideal sphere for the polymer particles of Example 5 and a deviation of approximately 76% for the inventive polymers (Examples 7 and 9).

  The gap break gap reading measured with a rheometer for each shampoo is used as a measure of the degree of "thread-like" rheology for each shampoo. By comparison of the gap readings for Examples 5-12 in Table 1, the shampoo gap reading, and the associated “thread-like aspect”, is more than for the highest molecular weight cationic acrylamide in Example 6. It can be concluded that it was larger and less for the lower viscosity cationic acrylamides in Examples 8 and 9. The “thread-like” characteristics of these acrylamide-containing cationic guar blends also decrease as the molecular weight of the cationic acrylamide decreases in the order of Example 10> 11> 12. The inventive polymers in Examples 13 and 14 in Table 1 are also low and medium MW in the shampoo formulations used in Table 1, as described in US7375173. This results in low string values for both polymers. These polymers produced a clear aqueous solution, resulting in an opaque shampoo of this formulation.

  The inventive polymers of Examples 9-12 in Table 1 also have very low unreacted acrylamide monomer compared to Comparative Examples 1-7.

(Examples 15 to 19)
The examples in Table 2 further illustrate the improved shampoo transparency of the polymers of the present invention. The inventive polymers in Examples 18 and 19 show the best transparency and little or no gel in the three surfactant systems, as indicated by the% transmission value> 95%. The comparative polymer in Example 15 shows a considerable gel. The comparative polymers in Examples 16 and 17 show a considerable gel and a decrease in transparency, as shown by the% transmission value of less than 90% in two of the three surfactant systems.

(Examples 20 to 26)
Interesting is the adhesion of antimicrobial and antifungal active compounds such as triclosan, zinc pyrithione and other zinc compounds to skin, hair and fabric substrates. Furthermore, the improvement in the deposition efficiency of silicone and other conditioning oils and fragrances on these substrates is also interesting. As shown in Table 3A, the model anti-dandruff shampoo containing the silicone emulsion (Table 3B) in Example 22 and the polymer of the present invention is more commercially available than the commercially available anti-dandruff shampoo product in Example 20. , Zinc is deposited on the artificial skin matrix. In addition, the shampoo containing the inventive polymer in Example 22 improved the conditioning feel of dry hair compared to the shampoo containing the higher MW cationic acrylamide in Example 21, and the shampoo's “thread” Like “feel” reduced. In addition, the inventive polymer in Example 23 provides more combined zinc and silicone to the Vitro-Skin substrate. A comparison between Example 25 and Example 26 shows that the lower MW polymer of Example 13 used in Example 25 is more vibrant for this terpolymer of the present invention with a higher combined zinc and silicone Vitro-Skin substrate. To bring it to.

(Examples 27 to 33)
The examples in Table 4 show improved silicone adhesion on the hair for shampoos containing a blend of cationic guar and cationic acrylamide compared to the cationic guar polymer alone. The improvement was particularly noted when the silicone concentration in the shampoo was reduced. As shown in Table 4, the blend compositions of Examples 30 and 31 maintained the wet and dry combing performance equivalent to the cationic guar in Example 29, while the Examples It produces significantly more silicone in the hair at 1.5 wt% silicone concentration than the individual cationic guar polymers in 29.

  In general, the distribution of silicone on the hair bundle is also interesting in that silicone adheres more preferentially at the root ends of the hair fibers and less in the middle and tip portions of the hair bundles that require more conditioning. As shown in Example 32 in Table 5, the shampoo of Example 30 resulted in a more desirable distribution of silicone along the hair fibers and contained the cationic guar shampoo composition of Example 29. It adheres less to the root ends of the fibers than the shampoo at 33, and more silicone adheres to the damaged hair fiber tips.

  The silicone distribution along the length of the hair bundle was measured according to the “silicone mapping” procedure described in the method section.

(Examples 34 to 45)
The unique enhanced deposition efficiency of the cationic synthetic polyelectrolyte polymer of the present invention is further illustrated by the results in Table 6 for conditioning surfactant compositions containing jojoba oil or meadow foam seed oil. It is. As shown in Example 40, the polymer of the present invention (same polymer as Example 30) brings the majority of jojoba and meadowfoam seed oil of all conditioning polymers in Table 6 to the hair. The synthetic polyelectrolyte polymer of the present invention in Example 43 also provides a large amount of jojoba oil and about the same amount of meadow foam seed oil as the polymer in Example 43 to the hair.

  As shown in Table 6 results for Example 44 and a comparison with Example 43, the synthetic polyelectrolyte polymer of the present invention reduces the amount of meadow foam oil in the shampoo by 30%. Even after the same amount of Meadowfoam seed oil is brought into the hair bundle.

  As shown in Example 44 of Table 6, the surfactant system containing the synthetic polyelectrolyte polymer of the present invention also provides a significant amount of jojoba oil to the synthetic skin model after the washing procedure. . Only the cationic guar of Example 39 provided a similar amount of jojoba oil from this surfactant system to the skin model matrix.

(Examples 46 to 60)
The enhancement of silicone adhesion on bleached / damaged hair by the synthetic polyelectrolytes of the present invention is shown in Table 7 and Table 8 (Table 10-11). The shampoo formulation used for the examples in Table 7 is the same formulation used for the examples in Table 6 containing a hydroxy-terminated silicone microemulsion. is there. The inventive polymer in Example 49 is deposited on a hair substrate bleached with 500-700 ppm of silicone. The inventive polymer blends in Examples 50 and 51 deposit 200-300 ppm of silicone on a bleached hair substrate. The cationic guar polymer in Comparative Example 48 deposits up to 100 ppm of silicone on the bleached hair substrate. The cationic hydroxyethylcellulose in Comparative Example 47 deposits up to 28 ppm of silicone on the bleached hair substrate. The control shampoo deposits less than 10 ppm of silicone on the bleached hair substrate. These results show the improved conditioning and adhesion performance of the polymers of the present invention.

  The examples in Table 8B were prepared using the ingredients in Table 8A. Improved conditioning of brown hair samples treated with shampoos containing polymers of the invention in Examples 56 and 57, and bleaching with these formulations compared to comparative examples in Table 8B The improved adhesion of silicone to the hair demonstrates the present invention.

(Examples 61 to 63)
The unique adhesion profile of silicone to untreated brown hair from 2-in-1 shampoo with the polymer of the present invention is shown in FIGS. In FIG. 1, the hair was prewashed with sodium laureth sulfate (2EO) surfactant prior to treatment with the silicone 2-in-1 conditioning shampoo. In FIG. 2, the hair was pre-washed with sodium laureth sulfate (3EO) surfactant prior to treatment with the silicone 2-in-1 conditioning shampoo. Example 61 contains the inventive polymer of Example 9. Example 62 contains the cationic guar polymer used in Example 10 and Example 63 contains the inventive polymer of Example 12. The results in FIG. 1 show that the inventive polymer in Example 12 deposits twice as much silicone on the untreated brown hair bundle as compared to the polymers of Examples 9 and 10. A lot of silicone spreads along the hair fibers to the middle and the ends of the hair bundles. However, in Example 61, the silicone adheres more uniformly along the length of the hair bundle and spreads to the damaged tip of the hair bundle.

Single fiber contact angle measurement
As shown in Table 9, a larger contact angle is observed for the tips of the hair fibers treated with the shampoo of Example 61 compared to the hair treated with the shampoo of Example 62. This result is consistent with the tip of the hair fiber in Example 61 being more hydrophobic than the tip of the hair fiber for Example 62. This data supports the results in FIGS. 1 and 2 showing that more silicone is brought to the hair fiber tips by the shampoo of Example 61 containing the polymer of the present invention.

(Examples 64-69)
As shown in Table 10, the inventive polymers in Examples 65, 66, and 67 compared to the cationic guar rinse in Example 68 compared to the control rinse (no polymer). Compared to the commercial conditioning rinses in Example 69 and Example 69, the combing energy in wet and dry states is significantly reduced for bleached hair treated with conditioning rinses containing these polymers.

(Examples 70 to 80)
As shown in Table 11, the polymers of the present invention bring amodimethicone conditioning agents from 2-in-1 conditioning shampoos to bleached hair. Bleaching of hair treated with a shampoo containing the polymer of the invention in Examples 76, 77, 79, and 80 with a control containing no cationic silicone in Example 70 and no polymer containing amodimethicone in Example 71 The lower moist combing energy value for the radiated hair indicates the conditioning provided to the hair bundle by the combination of amodimethicone and the polymer of the present invention. The polymers of the present invention in Examples 76, 77, 79, and 80 provide more conditioning to the bleached hair with the amodimethicone conditioning agent than the cationic cellulose polymer in Examples 72 and 73.

  The cationic guar polymers in Examples 74 and 75 also provide good conditioning to the bleached hair, as evidenced by the low wet combing energy observed for these polymers.

  Decreasing the amodimethicone level by 50% (comparing Example 79 with 80 and comparing Example 77 with 78) indicates that even after combing energy has reduced the amodimethicone level by 50%. And a decrease for the polymer of Example 80. This result suggests that even further reduction of amodimethicone can be achieved with the polymer of Example 80 while maintaining good conditioning performance.

(Examples 81 to 101)
Additional polymers of the present invention were prepared as shown in Table 12. For selected sets of these compositions, zinc adhesion to the Vitro Skin substrate was tested using a modified version of the formulation shown in Table 3A.

  As shown in Table 12, the polymers of the present invention in Examples 104-106 are compared to the commercial control anti-dandruff shampoo and to the commercial cationic guar polymer used for deposition. Then, more than twice the amount of zinc is deposited on the Vitro Skin substrate. Reducing the silicone particle size in the formulation affects the amount of zinc deposited on Vitro Skin, but the polymers of the present invention are even better than commercial shampoos and cationic guar benchmark polymers.

Standard Test Procedures Combability measurement of wet and dry hair is a typical test method used to measure conditioning performance in shampoo and conditioner applications. In skin care applications, skin smoothness or reduced or softer skin feel, reduced water vapor transmission and improved skin elasticity are test methods used to measure skin conditioning. In surfactant-based household cleansing product formulations (such as dishwashing detergents, fabric softeners, and anti-static products) that have desirable conditioning performance, conditioning is a softer feel to the fabric and provides an electrostatic effect. It means to eliminate the deformation known as breaking or flaking of fabric fibers. Giving the fabric color retention is also important and can be measured.

  Silicone adhesion from shampoos to hair bundles and zinc adhesion to artificial skin can be measured by several techniques. One technique used to quantify silicone adhesion to hair and one technique to quantify zinc adhesion to a solid substrate such as artificial skin is described below.

Silicone Adhesion Measurements Each 2-5 gram hair bundle sample was weighed to the nearest mg after removing the sample holder and placed in a clean 8 ounce jar with approximately 150 ml of methylene chloride. Samples were shaken at room temperature for 1.5 hours. The methylene chloride supernatant was filtered using Whatman # 41 filter paper, quantitatively transferred to a clean 8 ounce jar and evaporated to dryness with gentle heat and nitrogen sparging. Each sample was then dissolved in 2 ml of chloroform-d and transferred quantitatively to a 5 ml volumetric flask. Each sample was transferred to a 5 ml volumetric flask using 3 chloroform-d rinses. All flasks were diluted to the mark with solvent and inverted. Each sample was tested in a NICOLET MAGNA550FT-IR with 150 co-added scans at 4 cm-1 resolution and 0.4747 speed using a 0.1 cm-fixed path salt cell. The solvent band was subtracted using the chloroform-d reference spectrum (difference = 1.0). Silicone level measured peak height of Si-CH3 stretch at 1260cm-1 (baseline 1286 and 1227cm-1) followed by low level calibration curve ranging from 10 to 300 parts per million (ppm) And converted to mg / ml of silicone. Each sample was corrected for dilution volume and sample weight. All values are reported to the nearest ppm.

Silicone mapping along hair bundle length The relative concentration of silicone adhesion was mapped using surface infrared techniques, attenuated total reflection-infrared spectroscopy (ATR-IR). This technique can be used to qualitatively map the surface adhesion of silicone along hair fibers. ATR accessories are most commonly used with Fourier Transform Infrared (FTIR) spectrometers and are referred to as FTIR / ATR. This technique is a surface analysis method in which the depth of the analyte studied can vary from about 0.3 μm to 4 μm or 5 μm, depending on several factors including the ATR crystal angle, the refractive index of the ATR crystal, and the refractive index of the sample. It is. This technique measures the relative amount of silicone in the surface layer to a depth of 3 μm. The ATR-IR technique used in this study consists of the peak height of the silicone band near 796.5 cm ^-1 (tangent baseline) and the area slice of the hair reference band between 940.1 cm ^{-1 and} 919.9 cm ^-1 (tangent Baseline) ratio is used to determine the relative surface silicone level according to Equation 1. This method of surface silicone measurement has been shown to correlate with all extracted silicone levels over the range of 300 ppm to 4000 ppm. Ratio: peak at 796.5Cm ^-1 height / peak area (940.1cm ^-1 ~919.9cm ^-1 = relative surface silicone level (detection limit = 0.05) (Equation 1)

Using this technique, roughly 10-20 tresses of hair can be measured in a single measurement with a 1 mm circular spot. The fiber bundle from each hair bundle is placed on a Golden Gate ^* diamond ATR accessory of a Thermo-Nicolet MAGNA ^* 760FTIR spectrometer equipped with a deuterated triglycine sulfate (DTGS) detector. Infrared spectra are collected starting at the top of the hair bundle, down to the bottom, and collected at 12 different locations on the hair bundle.

Zinc and conditioning oil adhesion
Measurement of zinc on Vitro-Skin samples
1 gram of shampoo is layered over 20 grams of water in a 30 ml glass jar. The mixture is stirred for 10 seconds using a magnetic stir bar. The mixture is poured onto the center of a 2.5 sq cm Vitro-Skin® (IMS Inc., Portland, ME) that has been pre-hydrated (according to the manufacturer's instructions) and then removed on a Buchner funnel.
